Detailed Description

The embodiment of the utility model provides a can change extruder of extruding the shape to rubber fender, as shown in fig. 1-8, including

jar body

1, 1 left end fixed mounting of jar body has motor 2, and the motor 2 transmission shaft stretches into jar body 1 welding and has propulsion screw 12. The motor 2 rotates the propelling screw 12 to propel the raw material entering the tank 1, which is not described in detail since it is a conventional technical means. A feed inlet 11 is welded on the tank body 1. The right end of the tank body 1 is fixedly provided with a connecting pipe 3, and the connecting pipe 3 is fixedly provided with a forming nozzle 4. The raw material enters the tank body 1 and is extruded by the propelling screw 12 to be sent into the connecting pipe 3 and then sent out from the forming nozzle 4.

The nozzle 4 comprises a connecting base 41, two arcuate plates 42, a top plate 43 and a bottom plate 46. The connecting seat 41 is opened with an outlet 411 corresponding to the connecting tube 3. The connecting base 41 is screwed with the connecting pipe 3. With reference to fig. 4, the two arc plates 42 are respectively located at two sides of the outlet 411, the top plate 43 is located above the arc plates 42, the top plate 43 is in sliding fit with the connecting seat 41, and the top plate 43 can move up and down. The bottom plate 46 is located below the arc-shaped plate 42, and the bottom plate 46 is inserted into the connecting socket 41.

A support plate 44 is welded on the top of the connecting seat 41. And one end of the support plate 44 is welded with a spring 45, and the lower end of the spring 45 is welded with the top of the top plate 43. The arc 42 lower extreme is articulated with connecting seat 41, and arc 42 top fixed mounting has magnetic stripe 421, and roof 43 sets up the logical groove 431 with magnetic stripe 421 looks adaptation, and magnetic stripe 421 slides in logical groove 431. The connecting base 41 is provided with a vertical sliding groove 413, and the connecting base 41 is in sliding fit with the top plate 43 through the sliding groove 413. The connecting base 41 is formed with an insertion hole 412, and the bottom plate 46 can be inserted into the insertion hole 412.

Since the outlet 411 is circular, when a circular rubber fender is required, as shown in fig. 5, the bottom plate 46 is simply pulled out from the connecting seat 41. At this time, although the arc plate 42 is vertical, the top plate 43 is pushed by the spring 45 to press the arc plate, and the magnetic strip 421 slightly clamps the through groove 431, so that the arc plate 42 is prevented from rotating. When the arched fender is needed, as shown in fig. 4, the bottom plate 46 is inserted into the connecting seat 41, and the lower half of the outlet 411 is shielded by the bottom plate 46, so that partial discharge is limited, and the cross section of the raw material after coming out of the forming nozzle 4 is arched.

Similarly, when the cone-shaped fender is needed, as shown in fig. 6, the magnetic strip 421 is shifted to make the two arc-shaped plates 42 approach each other, and the magnetic strips 421 attract each other and cling to each other. The top plate 43 is tightly attached to the top of the arc-shaped block 42 by the spring 45, and the bottom plate 46 is pulled down. The arcuate blocks 42 block a portion of the outlet 411, thereby tapering the fender cross-section.

The outer side of the connecting pipe 3 is fixedly provided with a cooling mechanism 5, the cooling mechanism 5 is fixedly provided with a single chip microcomputer 6, and the single chip microcomputer 6 controls whether the cooling mechanism 5 works or not. The cooling mechanism 5 is communicated with a plurality of condensation pipes 51. The condensation pipe 51 is partially embedded in the connecting pipe 3. Since the cooling mechanism 5 is a conventional technical means and no improvement or innovation is made to it per se, the detailed structure, connection manner, and the like are the same as those of the prior art and will not be described in detail.

The condensing pipe 51 is contacted with the raw material to reduce the temperature to a certain degree, so that the phenomenon that the raw material is in a liquid state due to too high temperature and cannot be molded is avoided.

The end part of the connecting pipe 3 is fixedly provided with a temperature measuring pipe 7, and the temperature measuring pipe 7 is used for measuring the internal temperature of the connecting pipe 3. The pipe body of the temperature measuring pipe 7 is transparent, and corresponding numerical values are engraved on the surface of the pipe body. The bottom end of the temperature measuring pipe 7 is welded with a heat conductor, and the heat conductor at the bottom end of the temperature measuring pipe 7 is inserted into the connecting pipe 3. The piston 71 is matched with the inner part of the temperature measuring tube 7 in a sliding way, the piston 71 divides the temperature measuring tube 7 into an upper cavity and a lower cavity, and the lower cavity of the temperature measuring tube 7 is filled with air. When the temperature measuring device works, the temperature of the raw materials is in contact with the heat conductor, the temperature in the temperature measuring tube 7 gradually rises after heat transfer, and air is heated and slowly expands to push the piston 71 to move. The piston 71 is lowered as the air volume decreases after the temperature decreases. The temperature in the vertical reaction connecting pipe 3 passes through the position of the piston 71. Thereby allowing a person to determine whether or not the cooling mechanism 5 needs to be activated. The operation of operators is convenient.

As described above, in the extruder capable of changing the extrusion shape of the rubber fender, the arc-shaped block 42, the magnetic strip 421 and the top plate 43 are engaged with each other to shield the partial outlet 411 and to taper the discharge area. The bottom plate 46 is matched with the connecting seat 41 to shield the lower half part of the outlet 411, so that the discharging area is changed into an arch shape. Thereby the discharge area of the forming nozzle is correspondingly changed according to the requirement. Therefore, the purpose of manufacturing the fender with different cross sections is achieved, and the application range is further widened. The effect of manufacturing the fender with different shapes by one machine is realized.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
